JOHN WILSON, OF GENTSVILLE, SOUTH CAROLINA.

LOOM.

Speccaton of Letters Patent No. 6,487, dated May 29, 1849.

T0 all 'whom t may concern Be it known that JOHN VILSON, of Gentsville,in the district of Abbeville and State of South Carolina, have inventedcertain new and useful Improvements in Power-Looms, and that thefollowing is a full, clear, and exact description of the yprinciple orcharacter which distinguishes them from all other things before knownand of the usual manner of making, modifying, and using the same,reference being had to the accompanying drawing, in which- Figure l is aside elevation of the loom. My loom is made in all its parts like theordinary power loom except in the parts specifically described. Theobject of the invention being to dispensek with one of the shafts of theloom and all the cog gearing. The improvements consist in the shaft (a)commonly called the cam shaft, in the position usually occupied by thecrank shaft, and afliXing to each end thereof an apparatus which Idenominate the quadrangular wheel that are connected with the lay, so asto give two beats to every revolution of the shaft.

The construction and operation of this quadrangular wheel is preciselysimilar to the well known trammels for drawing elipses, and consists ofa wheel (b) in which two grooves (c) are formed at right angles to eachother and crossing at the center; in each of these` grooves there aresliding rlhe other parts of the loom are worked by cams in the ordinaryway attached to the same shaft. The quadrangular wheel may be formed ofany suitable metal, and the shafts may be driven by a loose pulleycoupled thereto by a common gland clutch fixtures that are too commonand well known by every machinist to require a particular descriptionhere.

Having thus fully described my improvement, what I claim therein as newand for which I desire to secure Letters Patent, 1s-

The combination of the quadrant, wheel, or trammel, with the cam shaftof a power .loom by means of which I can locate the said shaft in theposition of the crank shaft, and dispense with one shaft, and theordinary gearing connected therewith.
